You are correct Chris for stock injectors but JJ says stock nozzles and doesn't reference injector size. I have heard (though not confirmed yet) that Bill @ PHP has put down over 500hp (I think 510hp but don't quote me on that, I have two numbers in my head and that is the more conservative of the two) on 175/stock injectors with the Stage 2, his ECM tuning, and FICM tuning. Also, I personally have heard his truck idle when I was at TS and that thing is as quiet as a common rail. I dont know what all he has done to it for oil and fuel mods but it is NICE. Again not to try and put words in JJ's mouth here but just trying to offer that he may be referencing what I have heard as well.
